[PATCH 06/11] mtd: remove lart flash driver
From: Arnd Bergmann
Date: Fri Oct 21 2022 - 11:56:47 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
The sa1100 lart platform was removed, so its flash driver is
no longer useful.

- * Limitations:
- *
- * Even though this driver is written for 3 Volt Fast Boot
- * Block Flash Memory, it is rather specific to LART. With
- * Minor modifications, notably the without data/address line
- * mangling and different bus settings, etc. it should be
- * trivial to adapt to other platforms.
- *
- * If somebody would sponsor me a different board, I'll
- * adapt the driver (:
